        * configure.in: Remove target-libstdc++-v3 from noconfigdirs for
        *-*-netware, but add target-libmudflap.
        Consolidate *-*-netware targets (of which really only i?86 exists)
        into a single entry.
        * configure: Likewise.
gcc/
        * config.gcc: Resurrect NetWare as a target. Handle special case of
        Novell linker to be used (specified through --with-ld=) and threading
        model of either Posix (default) or NKS.
        * config/i386/i386.c (ix86_return_pops_args): Conditionalize popping
        of incoming hidden argument on KEEP_AGGREGATE_RETURN_POINTER.
        * config/i386/i386.h (KEEP_AGGREGATE_RETURN_POINTER): New.
        * config/i386/netware.c, config/i386/netware.h: New.
        * config/i386/nwld.c, config/i386/nwld.h: New.

        * config/i386/t-netware, config/i386/t-nwld: New.
        * gthr-nks.h: New.
        * doc/install.texi: Document NKS threading model.
gcc/cp/
        * g++spec.c (MATH_LIBRARY_PROFILE): Default to MATH_LIBRARY rather
        than "-lm".
gcc/testsuite/
        * g++.dg/abi/bitfield5.C: Use -mno-ms-bitfields.
        * g++.old-deja/g++.jason/thunk2.C: xfail for NetWare.
        * g++.old-deja/g++.law/profile1.C: xfail for NetWare.
        * g++.old-deja/g++.other/store-expr1.C: xfail for NetWare.

        * gcc.c-torture/compile/20001109-2.c: xfail for NetWare.
        * gcc.c-torture/execute/multi-ix.c: Use __builtin_bzero rather than
        the non-portable bzero.
        * gcc.dg/20010912-1.c: xfail for NetWare.
        * gcc.dg/20020426-2.c: xfail for NetWare.
